save our planet?
4. Do you know that the
quality of the environment
we live in depends on our
action?
Questions:

this?

D. Discussing New
Conceptsand
Practicing New
Skills#1
Expressthe relation
{
(−1,3),(3,4),(4,3),
(−4,2),(5, −1)
}
As a table andas a graph.Then
determine the domainandrange.
E. Discussing New
Conceptsand
Practicing New
Skills#2
Expressthisrelationasa table,
mapping,andgraph. List down
the domainand range of the
relation.
{(1,1), (2,3),(3,5),(4,7),(5,7)}
F.Developing
Mastery
(LeadsTo
Formative
Assessment3)
1. Expressthisrelation
{
(−2,−2), (3,0), (2,−1),
(4,1), (−3,2)
}
as a table and as a graph. Then
determine the domainandrange.
2. Expressthisrelation shown
on the graph as a set of
orderedpairsandin a
table.Thenfindthe
domainandrange.

The size of onthe a movie on
the screenand the distance of
the projectorfromthe screen
can be expressedasa relation.
The diagram at the right shows
that if the projectis 1 unitaway
fromthe screen,the size of the
picture is3 squares.
a) Expressthe relationas
a set of orderedpairs.
b) Describe the pattern
that existsbetweenthe
distance the projector
isfrom the screenand
the size of the picture.
c) Findthe size of the
picture if the projector
is10 unitsfromthe
screen.
d) Graph the relation.
